Observation of T = 3/2 isobaric analog states in ⁹Be using p + ⁸Li resonance scattering

NUCLEAR REACTIONS ¹H(⁸Li, ⁸Li), E(cm)=1.46-2.3 MeV, [secondary ⁸Li radioactive beam from ²H(⁷Li, ⁸Li), E=23.5, 27 MeV primary reaction]; measured energies of light and heavy recoils, (light recoils)(heavy recoils)-coin, differential σ(θ, E) using two annular Silicon strip detectors at RESOLUT radioactive nuclear beam facility of the FSU John D. Fox Superconducting Accelerator Laboratory. ⁹Be; deduced resonances J, π, width, T=3/2 IAS, spectroscopic factors from R-matrix analysis using MINRMATRIX code. Discussed isomirror properties for the T=3/2 A=9 isoquartet. Relevance to study of the structure of neutron-rich exotic nuclei through IAS.
